Features were classified according to SJRWMD modified FLUCCS. The 2006 seagrass Photointerpretation for the project was accomplished on Avineon's ImageStation Stereo Display (ISSD).
Seagrass cover type boundaries were photogrammetrically digitized using CadMap/dgn software in conjunction with ISSD, running on Pentium workstations with Windows 2000. This software directly captures digital data into MicroStation (Bentley Microsystems, Inc.) for later importation to ARC/INFO.
Photointerpreters utilized previously collected field data along with other available collateral data to assist in their interpretation. Throughout the photointerpretation process, positional accuracy of seagrass boundaries was maintained according to the photographic signatures apparent on the photography. The minimum mapping unit for classification is 0.25 acres (=0.1 hectares). The horizontal accuracy of the data meets NMAS for 1:24,000 scale maps (+/- 40 feet).A primary objective of the Indian River Lagoon (IRL) Surface Water Improvement and Management (SWIM) Plan is to protect and restore seagrasses. The IRL SWIM Plan directs the St. Johns River Water Management Districts to map seagrasses in the Indian River Lagoon at two to three year intervals. Accordingly, Indian River Lagoon seagrass maps have been prepared for the following years: 1986, 1989, 1992, 1994, 1996, 1999, 2001,2003 and 2005.
These lagoon-wide maps, based on aerial photographs, provide an overall picture of the seagrass resources in the IRL. These maps serve as important management tools for obtaining a current inventory of this resource, identifying "healthy" areas that may deserve special protection efforts, and identifying potential "problem" areas that require further investigation. The maps can also document large-scale trends in the status of this resource.200604052006060820062309REQUIRED: The year (and optionally month, or month and day) for which the data set corresponds to the ground.Source photography dateEvery 2 years.-80.975354-80.31721729.10231127.556690noneseagrassSAVbenthic habitatsubmerged aquatic vegetationIndian RiverIndian River LagoonIRLMosquito LagoonBanana RiverICWNoneAcknowledgement of Avineon Inc. would be appreciated in products derived from this data.

Pre-interpretation groundtruthing was also performed to aid in delineation and classification of photo signatures. Additional checks for valid attributes, as defined by the SJRWMD modified FLUCCS, were performed.Polygon and chain-node topology present.
NODEERRORS run with Dangle option. No dangles present.
UNSPLIT used to remove superfluous pseudo-nodes.
LABELERRORS run, with all polygons attributed.
RELATE was employed to check for contiguous arcs. No arcs have
the same attribute on both sides.Minimum mapping unit for seagrass, algae beds and
unvegetated bottom polygons is 0.25 acres. The study area boundary
for the project was defined by the SJRWMD. Features were captured
and classified according to the minimum mapping unit
guideline and the SJRWMD modified FLUCCS.Ground controlpoints were provided by the SJRWMD from the 1996, 1999 and 2003 mapping efforts. These points included both GPS survey points and control points collected from USGS 1m DOQQ's. Horizontal positional accuracy of the data meets NMAS for 1:24000 scale maps, approximately +/- 40 feet. Digital linework was reviewed over USGS DOQQ and the 2003 seagrass data. Well defined features on the images and 2003 data were inspected for comparison to 2005 linework collected representing those features. GPS points were also collected during 2005 seagrass field work at well defined features and compared against coordinates for the same features on the 2005 data.US ImagingIndian River LagoonAerial photography24000True color diapositives, stereo coverage200604052006120820062309calendar date(none)Photographic signature for interpretation
of seagrass data.Ground control points were taken from the 2005 mapping effort and 10 additional points were collected in the field during the 2005 mapping effort. The points were imported from 2005 IRL seagrass project. The 2005 ground control points provided the latitude and longitude coordinates for each point. These items were referenced to identify and transfer the points to the 2006 aerial photo layout. In 2006 Avineon had collected several new control points from USGS DOQQ's to densify the control network, filling in the gaps where necessary. The pixel coordinate values, which are embedded within the digital orthophotographic imagery, were collected for photoidentifiable features on the DOQQ image.
The values for the points provided from the 2005 project were expressed as geographic coordinates (latitude/longitude), NAD83, Feet. The values for the points collected from DOQ were expressed in UTM coordinates, NA83, Meters. All coordinates were transformed; using a conversion program called Corpscon, to Stateplane coordinates, NAD83, Feet.f:\sjrwmd\irl_05\work_in_progress\covers\final05UnknownDataset copied.f:\sjrwmd\irl_05\work_in_progress\covers\aa_finalcorr\final05_stpDataset copied.f:\sjrwmd\irl_05\work_in_progress\covers\aa_finalcorr\new_ folder\final05_testDataset copied.f:\sjrwmd\irl_05\work_in_progress\covers\aa_finalcorr\IRL05_utmMetadata imported.F:\SJRWMD\IRL_05\Final_Inspection\Final_delivery\irl05_utm\metadata.xmlDataset copied.f:\sjrwmd\irl_06\work_in_progress\covers\irl_06Metadata imported.C:\DOCUME~1\jmuller\LOCALS~1\Temp\xmlA4.tmpMetadata imported.C:\DOCUME~1\jmuller\LOCALS~1\Temp\xml14.tmpDataset moved.f:\sjrwmd\irl_06\final_inspection\final_delivery\irl06Metadata imported.C:\DOCUME~1\jmuller\LOCALS~1\Temp\xml48.tmpDataset moved.f:\sjrwmd\irl_06\final_inspection\final_delivery\irl_06Dataset moved.f:\sjrwmd\irl_06\final_inspection\final_delivery\cd_data\irl_06Metadata imported.F:\SJRWMD\IRL_06\Final_Inspection\Final_delivery\CD_DATA\Reports\irl_06 metadata.xml20080625Dataset copied.20090120VectorSimple4FALSE0FALSEFALSEcoordinate pair0.0000010.000001metersD_North_American_1983_HARNGeodetic Reference System 806378137.000000298.257222irl06Feature Class0FIDInternal feature number.ESRISequential unique whole numbers that are automatically generated.FIDOID400ShapeFeature geometry.ESRICoordinates defining the features.ShapeGeometry000IdIdInteger660
